• This is my VERY first class

How do we know that?

Because I used a function to find it

match("R", LETTERS)

## [1] 18

• R is a computing language
• It was born of the S language from Bell Labs in the 1970's
• R became the open source version of S in the 1990's
• It's well known for statistics
• But, modern implementations have become a powerful, multi-purpose language

From the R-Project Webpage:

Many users think of R as a statistics system. We prefer to think of it of an environment within which statistical techniques are implemented. R can be extended (easily) via packages. There are about eight packages supplied with the R distribution and many more are available through the CRAN family of Internet sites covering a very wide range of modern statistics.

• R provides an integrated environment for data science
• That means we can both process and visualize data in the same environment
• R is powerful and is growing
• There is a strong community around R
• That means help is available
• Most of all, I think R is approachable

• Participation
• Ideas
• Feedback
• Data
• Questions
• This class is interactive, so your engagement will make it better!
